ravel-google-oauth2-provider

Ravel AuthorizationProvider for Google OAuth2

Note: This module is currently untested.

Example usage:

app.js

const app = new require('ravel')();
const GoogleOauth2Provider = require('ravel-google-oauth2-provider');
new GoogleOauth2Provider(app);
// ... other providers and parameters
app.init();
// ... the rest of your Ravel app

Configuration

Requiring the ravel-google-oauth2-provider module will register configuration parameters with Ravel which must be supplied via .ravelrc or app.set():

.ravelrc

{
  "google auth callback url" : "http://localhost:8080",
  "google auth path": "/auth/google",
  "google auth callback path": "/auth/google/callback",
  "google client id": "YOUR_CLIENT_ID",
  "google client secret" : "YOUR_CLIENT_SECRET"  
}

Note that google auth callback url should be the external url for your application. Only change google auth path and google auth callback path if those routes collide with your application - otherwise they will receive the given default values.

You'll also need to implement an @authconfig module like this:

modules/authconfig.js

'use strict';

const Ravel = require('ravel');
const inject = Ravel.inject;
const Module = Ravel.Module;
const authconfig = Module.authconfig;

@authconfig
@inject('user-profiles')
class AuthConfig extends Module {
  constructor(userProfiles) {
    this.userProfiles = userProfiles;
  }
  serializeUser(profile) {
    // serialize profile to session using the id field
    return Promise.resolve(profile.id);
  }
  deserializeUser(id) {
    // retrieve profile from database using id from session
    return this.userProfiles.getProfile(id);
  }
  verify(providerName, ...args) {
    if (providerName === 'google-oauth2-web') {
      const accessToken = args[0];
      const refreshToken = args[1];
      const profile = args[2];
      // TODO something more complex, such as using/storing tokens
      return Promise.resolve(profile);
    }
  }
}

module.exports = AuthConfig;
